Definitions
- the present application relates to electronic devices, and in particular, to electronic patches that can adhere to human skin or the surface of an object.
- Electronic patches or stickers can be attached to human bodies and other objects such as merchandized goods such as computers, machineries, and clothes, packaging material and shipping boxes. Electronic patches can communicate with smart phones or other devices wirelessly, through NFC, Bluetooth, WiFi, or other methods. Tags wearable by people are a specific type of electronic patches.
- Electronic patches can be used for tracking objects and for performing functions such as producing sound, light or vibrations, and so on. As the applications and human needs become more sophisticated and complex, there are a rapidly increasing number of tasks that electronic patches are required to perform. Electronic patches are often required to be conformal to curved surfaces. In addition, the curvature of the human skin can vary overtime.
- Electronic patches and wearable tags can communicate with smart phones and other devices using WiFi, Bluetooth, Near Field Communication (NFC), and other wireless technologies.
- NFC is a wireless communication standard that enables two devices to quickly establish communication within a short range around radio frequency of 13.56 MHz.
- NFC is more secure than other wireless technologies such as Bluetooth and Wi-Fi because NFC requires two devices in close proximity (e.g. less than 10 cm).
- NFC can also lower cost comparing to other wireless technologies by allowing one of the two devices to be passive (a passive NFC tag).
- Bluetooth is another wireless technology standard for exchanging data over relatively longer distances (in tens of meters). It employs short wavelength UHF radio waves from 2.4 to 2.485 GHz from fixed or mobile devices. Bluetooth devices have evolved to meet the increasing demand for low-power solutions that is required for wearable electronics. Benefited from relatively longer reading distance and active communication, Bluetooth technologies allow wearable patches to continuously monitoring vital information without human interference, which is an advantage over NFC in many applications.
- Wearable patch is an electronic patch to be worn by a user.
- a wearable patch is required to stay on user's skin and operate for an extended period of time from hours to months.
- a wearable patch can contain a micro-electronic system that can be accessed using NFC, Bluetooth, WiFi, or other wireless technologies.
- An authentication wearable tag can be used as a “password” similar to a barcode. For example, it can recognize a user's smart phone for authentication purpose.
- a wearable patch can also be integrated with different sensors such as vital signs monitoring, motion track, skin temperature measurements, and ECG detection.
- a wearable patch often includes multiple rigid semiconductor chips and sensors have significant thicknesses assembled on flexible printed circuits to provide sensor, computation, and communication functions.
- the printed circuits are typically made of flexible polymer substrates that are not deformable enough to adapt to commonly occurring shape change, the high percentage of deformations of the user's skin, which is one reason for users' discomfort when they wear these wearable patches.
- the wearer's skin may interfere with their proper operations. For example, when an antenna is placed in contact with the skin, the antenna's communication range is significantly reduced. In one example, the wireless communication range of an antenna in contact with the skin is less than half the range if the antenna is placed just 4 mm away from the user's skin.
- EEG electroencephalogram
- body temperature sensors need to be in contact of users' skins to conduct measurements
- other sensors such as ambient temperature sensor are required to measure signals away from the user's skin.
- the ambient temperature if often different from the human body temperature that is in the range of 36-41° C.
- the presently disclosure attempts to address the aforementioned limitations in conventional electronic patches.
- the disclosed electronic patches are highly compliant and more stretchable, while also being able to support the circuit, chips, and other electronic components in the wearable electronic patches.
- the disclosed electronic patches can change their physical shape and dimension to relieve stresses such as repeated elongations, therefore increasing durability.
- the disclosed electronic patches can stay attached to skin for longer period of time enduring muscle movements while providing constant contact to the skin.
- the disclosed electronic patches are also breathable.
- the stretchability and the breathability make the disclosed electronic patches more comfortable for the users.
- the disclosed electronic patches are capable wireless communication with little interference from users' skins. Moreover, the disclosed electronic patches can conduct measurements both at users' skins and away from the user's skin. The present application further discloses simple and effective manufacturing process to fabricate such wearable electronic patches.

Abstract
Description
- The present application relates to electronic devices, and in particular, to electronic patches that can adhere to human skin or the surface of an object.
- Electronic patches or stickers can be attached to human bodies and other objects such as merchandized goods such as computers, machineries, and clothes, packaging material and shipping boxes. Electronic patches can communicate with smart phones or other devices wirelessly, through NFC, Bluetooth, WiFi, or other methods. Tags wearable by people are a specific type of electronic patches.
- Electronic patches can be used for tracking objects and for performing functions such as producing sound, light or vibrations, and so on. As the applications and human needs become more sophisticated and complex, there are a rapidly increasing number of tasks that electronic patches are required to perform. Electronic patches are often required to be conformal to curved surfaces. In addition, the curvature of the human skin can vary overtime.
- Electronic patches and wearable tags can communicate with smart phones and other devices using WiFi, Bluetooth, Near Field Communication (NFC), and other wireless technologies. NFC is a wireless communication standard that enables two devices to quickly establish communication within a short range around radio frequency of 13.56 MHz. NFC is more secure than other wireless technologies such as Bluetooth and Wi-Fi because NFC requires two devices in close proximity (e.g. less than 10 cm). NFC can also lower cost comparing to other wireless technologies by allowing one of the two devices to be passive (a passive NFC tag).
- Bluetooth is another wireless technology standard for exchanging data over relatively longer distances (in tens of meters). It employs short wavelength UHF radio waves from 2.4 to 2.485 GHz from fixed or mobile devices. Bluetooth devices have evolved to meet the increasing demand for low-power solutions that is required for wearable electronics. Benefited from relatively longer reading distance and active communication, Bluetooth technologies allow wearable patches to continuously monitoring vital information without human interference, which is an advantage over NFC in many applications.
- Wearable patch (or tag) is an electronic patch to be worn by a user. A wearable patch is required to stay on user's skin and operate for an extended period of time from hours to months. A wearable patch can contain a micro-electronic system that can be accessed using NFC, Bluetooth, WiFi, or other wireless technologies. An authentication wearable tag can be used as a “password” similar to a barcode. For example, it can recognize a user's smart phone for authentication purpose. A wearable patch can also be integrated with different sensors such as vital signs monitoring, motion track, skin temperature measurements, and ECG detection.
- Despite recent development efforts, conventional wearable devices still face several drawbacks: they may not provide adequate comfort for users to wear them; they may not stay attached to user's body for the required length of time; they are usually not aesthetically appealing.
- A wearable patch often includes multiple rigid semiconductor chips and sensors have significant thicknesses assembled on flexible printed circuits to provide sensor, computation, and communication functions. The printed circuits are typically made of flexible polymer substrates that are not deformable enough to adapt to commonly occurring shape change, the high percentage of deformations of the user's skin, which is one reason for users' discomfort when they wear these wearable patches.
- Another drawback of conventional wearable patches is that the rigid polymer substrate is not very breathable. The build-up of sweat and moisture can cause discomfort and irritation to the skin, especially after wearing it for an extended period of time.
- Moreover, conventional wearable patches are often not robust enough to sustain repeated elongations during body movements. Under stress, different layers in wearable patches can break or delaminate rendering the wearable patches inoperable.
- Another challenge for wearable patches is that the wearer's skin may interfere with their proper operations. For example, when an antenna is placed in contact with the skin, the antenna's communication range is significantly reduced. In one example, the wireless communication range of an antenna in contact with the skin is less than half the range if the antenna is placed just 4 mm away from the user's skin.
- In addition, while some sensors such as electroencephalogram (EEG) and body temperature sensors need to be in contact of users' skins to conduct measurements, other sensors such as ambient temperature sensor are required to measure signals away from the user's skin. The ambient temperature if often different from the human body temperature that is in the range of 36-41° C.
- There is therefore a need for more flexible wearable electronic patches that stick to skin longer, are comfortable for users to wear, and can perform intended functions at and away from users' skins so it is not affected by body temperature.
- The presently disclosure attempts to address the aforementioned limitations in conventional electronic patches. The disclosed electronic patches are highly compliant and more stretchable, while also being able to support the circuit, chips, and other electronic components in the wearable electronic patches. The disclosed electronic patches can change their physical shape and dimension to relieve stresses such as repeated elongations, therefore increasing durability. The disclosed electronic patches can stay attached to skin for longer period of time enduring muscle movements while providing constant contact to the skin.
- The disclosed electronic patches are also breathable. The stretchability and the breathability make the disclosed electronic patches more comfortable for the users.
- Importantly, the disclosed electronic patches are capable wireless communication with little interference from users' skins. Moreover, the disclosed electronic patches can conduct measurements both at users' skins and away from the user's skin. The present application further discloses simple and effective manufacturing process to fabricate such wearable electronic patches.

FIG. 1 , anelectronic patch 100 adheres to a user'sskin 110 for measuring body vital signs. Theelectronic patch 100 can be placed on forehead, hand, wrist, arm, shoulder, waist, leg, foot, or other parts of the body. In the present application, the term “electronic patch” can also be referred to as “electronic sticker” or “electronic tag”. - As discussed above, wearable electronic patches face several challenges: the user's
skin 110 may interfere with their proper operations. For example, theelectronic patch 100 may include an antenna for wireless communications with other devices. The antenna's communication range can be significantly reduced when an antenna is placed in contact with the user'sskin 110. In one example, the wireless communication range of an antenna in contact with the skin is less than half the range if the antenna is placed just 4 mm away from the user's skin. In addition, while some sensors (e.g. for EEG and body temperature measurements) need to be in contact of users'skins 110 to conduct measurements, other sensors such as ambient temperature sensor are required to measure signals away from the user'sskin 110. - Furthermore, people's daily activities such as taking showers or bathes, swimming, exercises, holding weights, etc. involve muscle and skin movements. The electronic patches thus need to responsively change their physical dimensions to be able to adhere to the skin for extended periods of time. The electronic patches may also be rubbed by clothing, hands, or other objects numerous times a day. While Band-Aid patches usually cannot on skin for more than a week, conventional electronic patches normally have much stiffer substrates, which makes them more easily rubbed off than Band-Aid stickers. Because drawbacks in this areas, some conventional electronic patches are not comfortable to wear because they are not stretchable, inflexible, and not breathable.
- In some embodiments, the presently disclosure aims to overcome the drawbacks in conventional electronic patches, and to provide highly stretchable, compliant, durable, and comfortable wearable electronic patches while performing intended sensing and communication functions at and away user's skins.
- One solution to the above mentioned challenges is to provide functions in two inter-connected electronic patches positioned at different distances from user's skin. Referring to

An insulating pad or spacer (not shown) can be disposed between the user'sskin 205 and thesensor 270 to insulate ambient temperature measurement from the user's body heat. While theelectronic patch assembly 200 can perform some intended functions, it requires two inter-connected electronic patches. The conductive line between the two electronic patches can easily be broken during user's body movements. - In some embodiments, the presently disclosure also provide simple structure and convenient manufacturing process for stretchable, compliant, durable, and comfortable wearable electronic patches that can perform intended sensing, actuation, and communication functions at and away user's skins.

Thesensing pad 530 is electrically connected to thesensor 520 by aconductive pin 535 through theelastic layer 505. - The
second portion 550 of theelastic layer 505 is defined by cut(s) 580 along two or more sides and is connected to thefirst portion 510 on at least oneside 585. The cut(s) 580, as described below, allows thesecond portion 550 to be lifted up and flip over thefirst portion 510 of theelastic layer 505. - A
spacer 560 is mounted on thesecond portion 550 of theelastic layer 505. A conductive circuit such as anantenna circuit 570 is bonded under or embedded within thesecond portion 550 of theelastic layer 505. Theantenna circuit 570 can include conductive line disposed in several wounds (e.g. in a helical shape). Theantenna circuit 570 and thesensor 520 are electrically connected by an electric circuit (not shown) embedded or on theelastic layer 505. - The
elastic layer 505 is made of a non-conductive material such as an elastomeric material or a viscoelastic polymeric material. Theelastic layer 205 can be made of a material having low Young's modulus and high failure strain. In some embodiments, theelastic layer 505 has Young's Modulus <0.3 Gpa. In some cases, theelastic layer 505 and can have Young's Modulus <0.1 Gpa to provide enhanced flexibility and tackability. Materials suitable for theelastic layer 505 include elastomers, viscoelastic polymers, such as silicone, and medical grade polyurethane that is a transparent medical dressing used to cover and protect wounds with breathability and conformation to skin. On the other hand, thesensors 520, thesensing pad 530, and theantenna circuit 570 are usually made more rigid materials. In some embodiments, thesensors 520, thesensing pad 530, and theantenna circuit 570 can have Young's Modulus larger than 0.5 Gpa, such as in a range between 1.0 Gpa-10 Gpa. - The flat
flexible circuit substrate 500 is used to as an intermediate preparatory structure for making a three-dimensionalelectronic patch 600, as shown inFIGS. 6A and 6B . Thesecond portion 550 of theelastic layer 505 is lifted up by opening the cut(s) 580, and flipped such that thespacer 560 is positioned on or above thefirst portion 510 of theelastic layer 505. Theside 585 stays connected to the rest of theelastic layer 505. The lifting and flipping of thesecond portion 550 leaves a void 590 in theelastic layer 505. - An adhesive can be applied on the
sensor 560 to allow it to adhere to thefirst portion 510 of theelastic layer 505. Theantenna circuit 570 is now on thesecond portion 550 and facing away from thefirst portion 510, thus minimizing interference from the user's skin as well as from other components in the three-dimensionalelectronic patch 600. Theantenna circuit 570 can substantially parallel to thefirst portion 510 or to the user's skin. - The three-dimensional
electronic patch 600 can be used to sense signals at a user's skin while transmitting wireless signals from an antenna away from the user's skin. Thesensing pad 530 and the lower surface of thefirst portion 510 of theelastic layer 505 are in contact of a user's skin. An adhesive layer can be applied under theelastic layer 505 to help stick to the user's skin. The adhesive layer can be pressure sensitive, which allows the compliant wearable patches tightly adhere to human skin under pressure, applied for example by a thumb. For instance, the adhesive layer can be made of a medical pressure sensitive adhesive. An example of such adhesive is medical grade tackified Hypoallergenic Pressure Sensitive Adhesive. - For example, the
sensor 520 and thesensing pad 530 can measure body temperature, EEG signals, pulse signal, and other body vital signals. Theantenna circuit 570 can transmit wireless signals to other devices. The thickness of thespacer 560 can be adjusted to minimize the interference of user's body to wireless transmissions. As discussed above, the radial range of wireless communication of the three-dimensionalelectronic patch 600 can double by keeping theantenna circuit 570 at 4 mm away from the user's skin in comparison to a conventional electronic patch in which theantenna circuit 570 being positioned near the user's skin. - The
antenna circuit 570, along with other components (such as an amplifier, a transceiver, a processor etc.) can communicate with external devices based on NFC standard, RFID, Wi-Fi, Bluetooth, or other types of wireless communication standard. Examples of external devices include smart phones, computers, mobile payment devices, scanners and readers (e.g. RFID readers), medical devices, security systems, personal identification systems, etc. Wireless communications compatible with theelectronic patch 200 include NFC in a frequency range near 13.56 MHz, UHF RFID at about 915 MHz, Bluetooth in 2.4 GHz or 5 GHz frequency ranges, and so on. - For example, the
antenna circuit 570 can transmit wireless signals to transfer sensing data measured by thesensor 520 to other devices, as well as receive commands from other devices. - The three-dimensional
electronic patches - The presently disclosed three-dimensional wearable electronic patches can provide sensing and communication functions away from the users' skins in addition to sensing and other functions in contact from users' skins. An advantage of the presently disclosed three-dimensional wearable electronic patch is that they can be easily manufactured from flat flexible circuit substrates instead of having to assemble multiple electronic patches. In one implementation, the disclosed three-dimensional wearable electronic patches can be packaged and shipped in flat configurations; the second portion can be partially lifted off and folded in the field to prepare the three dimensional structure.
- The presently disclosed three-dimensional wearable electronic patches are flexible and stretchable thus providing durability and more comfort to the users.
